SOAP CAKE.

SPECIFICATION formingpart of Letters Patent No. 648,247, dated April 24, 1900.

I Application filed May 4, 1899. Serial-No. 715,548.

To all whom it may concern:

Be it known that I, MATTHEW E. DUNNE, a citizen of the United States of America, residing at the borough of Manhattan, in the city, county, and-State of New York, have invented certain new and useful Improvements in (lakes or Bars of Soap, of which the following is a specification.

y invention has reference to improvements in cakes and bars of soap, and has for its object to provide as a new article of manufacture soap in cakes or bars containing a core placed substantially in the center of the cake or bar and made of material not soluble in water, such core being hollow and adapted to receive therein any matter for advertising or for other purposes and adapted to be opened for the removal of such advertising or other matter.

To this end my invention consists in a cake or bar of soap containing substantially at its center a core made of material substantially insoluble in water and consisting of two hollow sections placed together, so as to be capable of being opened or separated for inserting therein any matter for advertising or for other purposes, all for the purpose of preventing the removal of the core until the cake or bar of soap is substantially used up, such advertising or other matter then being accessible by opening or separating the sections of the core.

The nature of my invention will best be understood when described in connection with the accompanying drawing, which represents a longitudinal section of a cake or bar of soap embodying my invention.

Similar letters of reference designate corresponding parts.

Referring to the drawing, the letter A designates a cake of soap containing substantially in its center a core B, which is placed or embedded in said cake during the course of manufacture thereof. Said'core is made of material insoluble in water-such as wood,

rubber, bone, celluloid, glass, or the like-or of a material which is. only slightly soluble in (No specimens.)

water and which is not appreciably attacked by the soap. This core B is made hollow and of two sections aand b, which can be either entirely separated from each other or which may be connected by a hinge or hinges in a usual manner. The core may be made square, rectangular, cylindrical, or round, as desired. In the present example I have shown the core 5 5 composed of two concavo convex sections adapted to be snapped together and within which is contained the advertisement 0 or other substancesuch, for instance, as a conpon or a coin. When the soap is used up, the core B may be opened by separating the parts or by opening the same, according to the manner of fastening them together, and the matter contained therein removed. It Will be readily understood that by the use of this core waste of soap is prevented and also'that the cores may be used as a check in hotels and other large establishments or on trains on employees to whom soap is supplied for distribution for the use of guests or travelers by requiring the cores to be collected and returned. v

What I claim as new is- As a new article of manufacture, a cake or barof soap containing'substantially at its center a core made of material substantially insoluble in water and consisting of two hollow sections placed together so as to be capable of being opened or separated for inserting therein any matter for advertising or for other pur- 8'0 poses; all for the purpose of preventing the removal of the core until the cake or bar of soap is substantially used up; such advertising or other matter then being accessible by opening or separating the sections of the core, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

MATTHEW DUNNE.
